Abstract
L'anomalie isotopique de l'ozone observée au début des années 1980 a été la première manifestation de fractionnement isotopique indépendant de la masse d'origine chimique. Attribuée au départ, essentiellement au processus de formation de l'ozone, les travaux récents mettent en évidence d'autres contributions telles que la photodissociation. Cette thèse utilise une approche théorique basée sur des calculs ab initio de chimie et dynamique quantique pour déterminer les sections efficaces d'absorption et leurs variations isotopiques. Ces sections efficaces permettent d'étudier la photodissociation de l'ozone par irradiation du soleil (flux actinique) ; ce qui permet une évaluation précise du processus de photodissociation à l'enrichissement isotopique de l'ozone. Ces résultats pourront être intégrés dans un modèle global prenant en compte à la fois les processus de formation et de destruction de l'ozone.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
